摘要:Abstracta Catalyst System Consisting Of The Palladium(0) Complex Pd2(Dba)3 And Tri(P‐tolyl)Phosphine Was Found To Efficiently Promote The Decarboxylation Of Allyl Benzoates With Formation Of Allylarenes. This Catalytic Co Activation Followed By Extrusion Of Carbon Dioxide And Cc Bond Formation Represents A Sustainable Alternative To Traditional Waste‐intensive Cross‐couplings. The Scope Of The Transformation Includes Allyl And Cinnamyl Esters Of Various Ortho‐substituted Benzoic Acids. For Particularly Activated Substrates,The Palladium Catalyst Can Optionally Be Replaced By An Inexpensive Nickel Complex.Magnified Image

摘要:The invention pertains to the use of Group 8 transition metal carbene complexes as catalysts for olefin cross-metathesis reactions. In particular, ruthenium and osmium alkylidene complexes substituted with an N-heterocyclic carbene ligand are used to catalyze cross-metathesis reactions to provide a variety of substituted and functionalized olefins, including phosphonate-substituted olefins, directly halogenated olefins, 1,1,2-trisubstituted olefins, and quaternary allylic olefins. The invention further provides a method for creating functional diversity using the aforementioned complexes to catalyze cross-metathesis reactions of a first olefinic reactant, which may or may not be substituted with a functional group, with each of a plurality of different olefinic reactants, which may or may not be substituted with functional groups, to give a plurality of structurally distinct olefinic products. The methodology of the invention is also useful in facilitating the stereoselective synthesis of 1,2-disubstituted olefins in the cis configuration.

摘要:Provided are new functionalized nitrile rubbers, which may optionally also be in partially or wholly hydrogenated form, and also a process for preparing them by metathesis of nitrile rubbers in the presence of a metathesis catalyst and at least one functionalized allyl compound. The new functionalized nitrile rubbers are suitable for producing vulcanizable mixtures and allow the production of vulcanizates having very stable networks. Also made possible, in particular, is the synthesis of block copolymers.
